The couple's busy schedules have kept them apart over the past few weeks — Liam is stationed in Canada while he films the thriller Cut Bank with John Malkovich and Billy Bob Thornton, and Miley has been promoting her hit single "We Can't Stop" in the States. In addition to the quirky music video, Miley is getting even more attention from a big star shout-out. She took to Twitter this week to share her excitement over being mentioned in a track from Jay-Z's Magna Carta Holy Grail, saying, "Call it what you want. But I don't see Mr. Carter shoutin any of you b*tches out. #twerkmileytwerk."
